Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Alglucosidase alfa is a recombinant form of human acid alpha-glucosidase (GAA) that hydrolyzes glycogen to glucose in lysosomes. It replaces deficient GAA enzyme activity in patients with Pompe disease.
Recombinant adenosine deaminase (ADA) enzyme replacement therapy; degrades adenosine and deoxyadenosine, reducing toxic metabolites and restoring immune function.
20 mg/kg IV every 2 weeks.
25 mg/kg body weight administered intramuscularly once weekly.

The terminal elimination half-life of alglucosidase alfa is approximately 2.3 hours at steady state. This short half-life necessitates weekly intravenous infusions to maintain therapeutic enzyme levels in target tissues.
Terminal elimination half-life is approximately 3-6 months (mean ~100 days) in patients with PEG-ADA deficiency; clinical context: sustained enzyme replacement allows weekly or biweekly dosing.
Renal elimination is the primary route of clearance for alglucosidase alfa. Following intravenous administration, the drug is cleared via catabolism into small peptides and amino acids, which are then excreted renally. Less than 5% of the administered dose is excreted unchanged in urine. Biliary/fecal elimination is negligible.
Renal excretion of unchanged drug and metabolites: approximately 100% eliminated renally; no significant biliary/fecal elimination.
